Early movers: GM, CAT, AMZN, UPS, AAPL, FB & more

General Motors (GM)-The auto giant reported first quarter profit of 29 cents per share, two cents above estimates, with revenue falling short of consensus. Excluding items, the company earned six cents per share, down sharply from a year ago. GM's profits were impacted by recall costs, but strong pricing helped support the bottom line.

3M (MMM)-The company reported quarterly profit of $1.79 per share, a cent below estimates, with revenue also shy of consensus. That notwithstanding, the company called the quarter "solid" and maintained its full-year forecast.

Caterpillar (CAT)-The heavy equipment maker beat estimates by a mile with quarterly profit of $1.44 per share. Excluding restructuring costs, the company earned $1.61 per share, with sales also exceeding analyst predictions. Cost cuts helped Caterpillar increase its profits even as it deals with a continuing slowdown in its mining equipment business.

United Continental -The airline lost $1.33 per share for the first quarter, a loss that was two cents smaller than expected. Revenue was very slightly below analyst consensus.

UPS (UPS)- The shipping giant reported quarterly profit of 98 cents per share, ten cents short of estimates, with revenue shy as well. UPS said unusually harsh weather shaved about $200 million off first quarter profit.

Apple (AAPL)-The iPhone maker reported second quarter profit of $11.62 per share, well above estimates of $10.18, with revenue also exceeding estimates. The company also raised its quarterly dividend by eight percent to $3.29 per share, increased its stock buyback program to $90 billion, and announced a seven-for-one stock split.

Under Armour (UA)-The athletic apparel maker earned six cents per share for the first quarter, two cents above estimates, with revenues well above consensus as well. The company also increased its yearly earnings forecast, as sales in areas like golf and basketball rise.
